[ Nightly Build Regression ] - Arduino CLI will not use the default configuration .yaml file

[ubidefeo]

We recently introduced a regression which ended up in the latest Nightly.

The current Nightly build will not take the config file in consideration, so it won't be possible to search for boards and install them unless you pass in a path to the correct configuration file

the temporary workaround is to add --config-file as a flag

In my setup I run
arduino-cli config dump --config-file $ARDUINO_PREF/arduino-cli.yaml
arduino-cli core search samd --config-file $ARDUINO_PREF/arduino-cli.yaml

We'll be patching this tomorrow, apologies for any inconvenience if you're testing a NIghtly Build.
Reminder: do not use Nightly Builds (or Alpha, for what it's worth) in your production setup :D

thanks

I think this could be closed, we reverted the culprit commit and refactored how configs are handled to reimplement the wanted features with #1027.
